摘要： Techniques for distributing network traffic from an access server to a service gateway include receiving, at a load balancer, sticky table data that indicates an association between a particular subscriber IP address and a particular subscriber-aware service gateway in a gateway cluster. An input data packet is received with an input source address and an input transport-layer destination. If it is determined that the input transport-layer destination indicates a type of payload that uses a service gateway, then the particular service gateway associated with the particular subscriber is determined based on the sticky table and IP address in the input source address. An output data packet is directed to the particular service gateway using a link-layer or networking-layer destination address. These techniques allow a load balancer to be located anywhere on the network and to bypass a subscriber-aware service gateway for some data traffic.

摘要： Techniques for distributing control plane traffic, from an end node in a packet switched network to a cluster of service gateway nodes that host subscriber-aware application servers, include receiving a control plane message for supporting data plane traffic from a particular subscriber. A particular service gateway node is determined among the cluster of service gateway nodes based on policy-based routing (PBR) for the data plane traffic from the particular subscriber. A message based on the control plane message is sent to a control plane process on the particular service gateway node. Thereby, data plane traffic and control plane traffic from the same subscriber are directed to the same gateway node, or otherwise related gateway nodes, of the cluster of service gateway nodes. This approach allows currently-available, hardware-accelerated PBR to be used with clusters of subscriber-aware service gateways that must also monitor control plane traffic from the same subscriber.

摘要： In one embodiment, a method includes receiving, at a local node of a network, a sequenced data packet of a flow made up of multiple sequenced data packets from a source node directed toward a destination node. The flow is to be parsed by the local node to describe the flow for administration of the network. Based on sequence data in the sequenced data packet, it is determined whether the sequenced data packet is out of order in the flow. If it is determined that the sequenced data packet is out of order, then the sequenced data packet is forwarded toward the destination node before parsing the sequenced data packet. The out of order sequenced data packet is also stored for subsequent parsing at the local node.

摘要： Techniques for responding to intrusions on a packet switched network include receiving user data at a subscriber-aware gateway server between a network access server and a content server. The user data includes subscriber identifier data that indicates a unique identifier for a particular user, network address data that indicates a network address for a host used by the particular user, NAS data that indicates an identifier for the network access server, flow list data that indicates one or more open data packet flows, and suspicious activity data. The suspicious activity data indicates a value for a property of the open data packet flows that indicates suspicious activity. It is determined whether an intrusion condition is satisfied based on the suspicious activity data. If the intrusion condition is satisfied, then the gateway responds based at least in part on user data other than the network address data.

摘要： Techniques and systems for server farm load balancing and resource allocation are disclosed. In one embodiment, a method of load balancing can include: arranging servers into service groups; receiving an access request with information related to a differentiation between the service groups; selecting one of the service groups based on a mapping comparison to the information; and selecting one of the servers within the selected service group based on a hardware utilization comparison. The servers can include GPRS (General Packet Radio Service) Gateway Support Node (GGSN) or Remote Authentication Dial In User Service (RADIUS) servers, for example. The information can include an Access Point Name (APN) or Calling Station ID, for example.
